there are 100 students in a hostel .food provision for them is 20 days .how long will these provisions last ,if 25 more studens join them

Answer 1

the food will last for 16 days

Answer 2

Hey sup!

As per the question,

Let's suppose a student eats 1 unit of food in a day.
So 100 students eats 100*1=100 units/day.
For 20 days total provisions=100×20=2000units.

If 25 students join in
Increased provisions per day = 125*1=125 units.
So provision will last 2000/125= 16 days.

Hope it helps.
